ADAPTER ASSEMBLY FOR A WELL SYSTEM

摘要

An adapter assembly for a well system includes at least one coupling member having a passage formed therein and an adapter including a neck duct formed thereon. The neck duct is received in the passage of the coupling member forming a substantially fluid-tight seal therebetween. At least the adapter is formed from a lead-free material, minimizing a weighted average lead content of the adapter assembly.

1. An adapter assembly for a well system, comprising:
an adapter configured to be disposed in a casing of a well, the adapter including an outwardly extending duct, wherein the adapter cooperates with a first coupling member to facilitate a flow of a fluid from the well, wherein the adapter includes at least one of a substantially planar mating surface located on a face of the duct and a housing formed from a substantially lead-free material, and wherein a weighted average lead content of the adapter assembly with respect to wetted surfaces of the adapter and the first coupling member is no more than about 0.25 percent.
